Yes.

No.

But it seems genuinely to come through "yahoo" (judging by the "Received:"
field as it hops over the garden wall into our jurisdiction).

We've been seeing it for several days.  The content seems too random for
Bayes to do anything systematically reliably with it.  And the embedded
URLs seem to hop about, possibly too fast for the blacklists (accessed via
SA) to keep pace.  (We also use "spamhaus", via JANET, to do MTA blocking,
which may stop some; but there's a lot still gets through.)

I wonder how much Yahoo are doing to try to block it?
